WitrynaThis matrix F can also be obtained from the incidence matrix A by changing either of the two1s to −1 in each column. The above arguments amount to arbitrarily orienting the edges of G, and F is then the incidence matrix of the oriented graph. The matrixF is then the modified definitionof the incidence matrix A. Witryna9 kwi 2024 · All graphs, considered in this paper, are looples, without multiple edges, non-oriented or partially oriented graphs.
